Restore3 fails to resolve a P2P ref

[srivatsn]

I am trying to run restore3 on a project like this:

• There’a TestApp.csproj which is targeting NETCoreApp 1.0 and still uses project.json for dependencies (no TargetFrameworks property in the csproj).
• This has a <ProjectReference Include=”..\TestLibrary\TestLibrary.csproj” />
• The TestLibray targets netstandard1.5 (again project.json – no TargetFrameworks)

restore3 fails for this project saying it is unable to resolve the P2P for .NETCoreApp 1.0. This is the error from the log:

  Unable to resolve 'C:\sdk\bin\Debug\Tests\It_builds_the_project_successfully\AppWithLibrary\TestLibrary\TestLibrary.csproj' for '.NETCoreApp,Version=v1.0'.
